aThus, in addition to carbon, oxygen and nitrogen were scanned for as well as potassium in the treated samples. 因此,除碳之外,氧气和氮气为并且钾在被对待的样品被扫描了。[translate]
DefectCharge transferPolymeric carbon nitride (CN) is a cheap and visible-light photocatalyst for potentially real application of CO2 photoreduction into solar fuels. However, CN prepared by conventional one-step method always shows serious charge recombination and low charge mobility. Herein, we use ...
Step 2 Burn this organic material in a container that is well-ventilated, as oxygen is necessary for these chemical reactions. This oxygen will combine with the carbon within the organic material to produce the CO3, or carbonate, part of the potassium carbonate. Step 3 Transfer the ash, when...
Ammoniacal copper(I) chloride is an excellent absorption reagent and can be used to determine oxygen in concentrations of over 80%, provided carbon monoxide, unsaturated hydrocarbons, and acidic gases are absent. The usual absorption reagent for carbon monoxide is a solution of copper(I) chloride...
In organic synthesis, it is an extensively used reagent for the alkylation and arylation reactions on carbon, sulfur, nitrogen, and oxygen centres. It is also used in aldol condensation, Michael reaction, acylation, Wittig reaction, Knoevenagel reaction, elimination reaction, epoxide opening, ...
An improved electrode for use in oxygen determination is disclosed. Interference from carbon dioxide is eliminated by combining an improved electrolyte with means for permitting rapid electrolyte movement into and out of the space between the cathode and the membrane covering the cathode to maintain the...

Bax inhibits Kv1.3 via interaction of lysine 128 with the channel pore, resulting in IMM hyperpolarization and the release of reactive oxygen species (ROS). ROS might play multiple roles in apoptosis such as the dissociation of cytochrome c from the IMM and the permeability transition pore (PTP...
Heteroatom doping, especially N doping, could further promote their electrochemical performance, and the type of doped N configuration plays a key role in determining the reactivity of doped carbon. However, achieving a high proportion of active N (pyridinic N) in N doped carbon is still a big...
